Why are they all so, depressing? All of them could have amounted to something yet you decided it would be a good idea to add something SILLY too them or give them retarded names.
Lets take the first one, Depression.
Why do you need to name it something so; Unoriginal & Stupid. If your feeling depressed go sort it out, the female face is done fine; Dont need any other bullshit in there, just work on the face and then add a body or something. Go buy some colouring pencils or artists brushes/paint.
Shadow-Blade,
This is the one I am most disapointed with, if you hadent have put that god awful black shit spewing from his wrist and just kept and worked on the hand it would have been a masterpiece, again buy some colouring pencils or some shit.
Talk of Trees,
Nice tree shape, needs some foilage (THE GREEN STUFF OR OTHER COLOURED STUFF DEPENDING ON SEASON ONTOP.) To make it less depressing and silly. REFER TO BOLDED LETTERING ABOVE.
