Hey, thanks a lot for your comments.
I like what you have going, but if I could comment on anything it would be your approach to painting. Like others said, I would watch your values. Value control can be tricky when jumping straight into color (the classical masters used to do an underpainting entirely monochrome to work out their values, and sneak up on color via glazing). I would suggest doing tons of monochrome paintings before going directly into full chroma painting. This way you can focus entirely on drawing, values and brushwork. It's not a remedial thing to do, all the greatest painters trained themselves this way (Sargent, Zorn, even modern painters like Schmid and Burt Silverman) and I promise you will see a great improvement when you sit down to do your own thing. Also working with a limited palette can help tremendously with understanding nuances of color temperature. I would suggest reading Alla Prima by Richard Schmid. In my mind, there is no better book on painting.
