His left arm looks too short to me, unless you intended it that way.

By claw, do you mean a mechanical hand?  What material is it made out of?  If it is made out of metal, I would make it more metalic looking.  If it is supposed to be flesh colored, I might just change the color anyway to make it clear that it's not a real hand.

What type of game is this character intended for?  The character has to fit the game, so it would be easier to evaluate the character if we knew what the game was about.  Will it be about an unemployed man looking for a job?  Perhaps a recently laid-off engineer?  That's what the character suggests to me.  That could be a good game if you do a good job at it.

Some people first come up with the idea for a game, then create characters for it.  Others come up with the character first, then figure out what would be a good game for them to play in.  You seem to be doing the latter.  So decide what type of character you intend, then it will be easier to decide whether your sprite is appropriate for it.
