This is nothing to sneeze at! I like it! I think the only thing really in need of fixing in the painting is the bright blue: it is so discordant with the rest of the color scheme, which could be a point of interest, but it's too bright for the environment; in this atmosphere, realistically speaking, there would be red/yellow highlights & shadows over that blue, so it would not seem so bright. Something to play with?

Great job! Did you have fun making it?
