I'm a huge fan of anything space themed and this is definitely pleasing to look at. With the glowing effect of the window and the lighting on the character makes it feel like she's in a cozy environment. Excellent work, friend.

Interesting piece, the circular space window reminds me a lot of the one you see in the boss battle against N.Gin in Crash 2. haha

Anatomically speaking, it's all looking good! Her right hand looks slightly smudged, but upon closer inspection I can see that there really wouldn't be any knuckle definition considering the available light sources.

The only thing about this piece that could be pushed is probably just the contrast. As it stands it's a fine piece, but getting the darkness of space behind Ruby with some slightly deeper shadows would create a nice range of colours that would also further emphasize the lights and glowing of the technology of the space window. Extra darkness in the background would also allow for some other heavenly bodies to be drawn or some extra stars. Something to get the vastness of space down y'know? :P

Of the same vein, extra light and darkness on her braids would go a long way to add to the pseudo-realism you're going for while still keeping that painter-ly touch.

All in all a great piece and I look forward to the next one. :)

lofi is gud
