I actually quite like it.
~ Title ~
A-Bot, not too original is it? I know the picture is of A-Bot, but coming up with a more creative title could be nice. I really can't complain much as I can't really think of anything else to replace the generic title, but that being said, an artist who takes pride in their work should be taking pride in naming their artwork as well. Like I said though I won't get into this anymore because even I have been known to come up with some generic names. For example, Pyroscape.
~ Background ~
I love drawings of characters, but what I love more is when the character is placed in some sort of environment. Having A-Bot be a bit smaller could come in handy so you could have put him in the audio portal. What might have been cool would have been to make a city resemblance of the audio portal and place A-Bot in it. You could also take this even take this further by taking some popular audio submitters and making cartoon versions of them to put as his "gang" in the background behind him, backing him up.
~ Focus ~
Of course without any sort of background the main focus of this picture is A-Bot. The main focus of A-Bot to me though is the upper body. I feel that you did a superb job of the upper body! There is even some facial expression in this character, which is great as it's a robot and everything.
To me the lower body does have some proportion mistakes. On the left upper leg it's turned towards the front and the bottom is faced off to the left. Now for a human this would be a nasty impossible twist as it seems the pivot section of the hip would be dislocated and the knee it just twisted weird. It is a robot though so twists and turns can be alright since it has the ability to turn in ways that a person wouldn't be. I'm just not sure that's what you wanted.
~ Meaning ~
As the picture is itself there is little to no meaning behind it. There is this expression that comes from the facial structure though. He has this type of serious no-nonsense look, which really isn't the newgrounds type, but meh, he's a robot right? The comments that I made about the backgrounds might add some meaning to the submission.
~ Overall ~
It's a decent submission all around and pretty good if you were just trying to get back your rusty drawing skills.
The Good:
The color is good.
The upper body is great.
Good serious look.
Good line work.
Improvements:
Some proportion problems in the lower body.
A background and meaning would be great.
Add some originality to an already generic thing in some way.
Other:
Why not go ahead and do all of the Newgrounds Bots? I think you have the drawing potential to do them all and with some background work they could help you become scouted quite easily. :)
