Alright, where to start...
Well, first off, I don't see any resemblance to the D&P hero - if anything, more to Red, Ash or the main hero from R/B/G/Y with a recoloured shirt from Brendan/Ruby/Male hero of R/S/E...
Now, onto the actual critique. First off, scale. I myself have problems with scale as well. The head of your character is far too small. It's odd and creepy looking. The hands are far too squashed, it looks like the actual palms were shortened. The arms seem a bit odd, but it might just be scale or the head throwing the picture off... They are definitely too skinny, though, and flat. Arms have SOME curve, especially near the elbow.
And try not to colour with markers or draw on lined paper. Marked bleed and smudge, and it looks really ugly. And line paper is distracting and too easily wrinkled. If anything, just buy a pack of printer paper.
