I Like What he has done with the tank and character.
As you said he has beefed it but keepin the original Underground feel.
However The text is the part that needs some work.
I don't feel that the font fits the character of the logo completely.
It comes close but its not the spot on feeling i am getting.
The other thing is that the text could have a little more body.
The Balance is a little off.
If you are gonna stick with this font, take a close look at the spacing between the
first E and the W its optically a bit too wide.
Anyways Good luck witj the design proces and with the Building I ll get back to you soon with a very good game I'll get in contact with you soon.
Greetz and Good luck
