very great job

It looks a lot like rikis keyblade doesn't it?

A little simple ? Amateurish ! .... 8D I'm joking, to speak frankly, I never saw something like that... Dream who just came true ?

this is awesome *___* great work!

It looks realy realy nice . good job

Quick progress! Nice to see how it's coming along.^^

You're right about the lighting being not ideal due to the season, esp now in the paint stage, it's hard for me to see if you've the right colors.

Have you thought about making a simple fluorescent light system where you work (I assume the garage)? I made one with my partner a few years ago and it was really quite easy and fairly cheap; a fluorescent light base, the light rods, furnace duct cut down the middle and spread like a reflector, two threaded rods keep the reflector separated and it hooks up to metal chains. Easily moveable/adjustable. I used to use it for plants (it worked very well) but now I've set it up for future display/photos. [I'm not much of a gardener these days. :S]

That aside, IF the colors are accurate in the photo to the ref image then I'll say this:

You seem to be missing opaque colors on some blade/wing tips. Especially the two far points just right of the eye. From the ref, they should look like they're a lichen grey/green tone fading into magenta, then black points.

The magenta you have painted on the blades/wings (whatever they're called) in the area around the eye (not the eye itself) at various places looks like it should be redder/warmer. Same with the other blade upper mid-right (the one with the big grooves or 'steps') which should also be a slightly lighter pastel/pink. Kinda like faded pomegranate.

The 'feather' types near the top left look good so far, could be better with a stronger highlight, smoother blending, and I'll note in the ref one of the feathers reveals that it is angled down the middle. (It's mid-way down, very pointy, to the right of the dark feather gap). Another hint of this ridge it is the topmost one at that panel, which looks like its other half is hidden in shadow. This would mean that your groove there, was actually supposed to be a ridge. Though such detail is usually hard to spot in the carving/planning stage and I didn't even notice it either till now. Ah well.

The top doesn't look worked on yet so not much to critique there right now. I will say however it would definitely benefit from an acrylic's mottling effect. Acrylic just rocks with that.

The handle and pommel look like they could be more of a brassy hue. Though I think you did a great job there on the highlights anyways. They really 'pop'.

The eye looks like it could be a bit warmer/redder and lighter - my guess is you might soon be painting over/around the inner purple ring, so maybe you've already got that part planned out. I'm curious if you'll be painting the white highlight or leaving that up to the resin.

The top half of the sword itself looks like it could use more purple/brown hue overall, rather than the grey/black mottled it appears to be. I also realize the flatness of the paint is due to not having the coating on yet. Can't wait to see how much it'll shine.

Having painted with acrylics for quite a few years now I totally understand how difficult it can be to spread the paint in an even manner. But there are special acrylic spreaders that can do this very job with a lot less effort. It does cost some, but the blend effect is much nicer. Just something to consider.

Overall, I think you're doing a wonderful job, especially for having one small ref piece. Also, it's just nice in general to see Fan Art in a 3D setting. Really makes these worlds come to life.^^
