Tree house

Something I've been working on and off for 2 weeks. Have been really lazy with it hence the progress was FREAKIN slow =___= But had fun studying various style in panting tree trunk I keep going back and painting the gray scale layer, though I know I should be doing the coloring already but.......sigh~

Need comments and critique please! I'm really stuck with this! TT____TT

I kept forgetting this >< finally uploaded the finished version! Somehow I think it still lacks some colors...hmmm...
