My first modified custom! Punch/Counterpunch!

So I've done repaints and whatnot in the past, but I've never really gone so far as to actually mod a figure. I thought I'd start with everyone's favourite Sunstreaker/Sideswipe bash, Punch/Counterpunch!
Using Sunstreaker, because a place in town had a few on clearance, and with a cheap airbrush (one that uses canned air as opposed to a full compressor type unit) I sat down at my hobby desk usually reserved for my Gundam models, brought up some visual reference of G1 P/CP and the artwork for the upcoming club exclusive on my computer, and got down to business.
Here's what I came up with:
In vehicle mode with Sideswipe and Sunstreaker

Side View:

...and the custom plate:

Robot mode: Punch
Posing with Sideswipe and Sunstreaker

Close up

Counterpunch:
Standing over the wrecks of Sideswipe and Sunstreaker

Close up:

There's one more step I'd like to do before considering this one "done", I've ordered some rubsigns off of reprolabels.com to add an Autobot one to Punch's chest, and a Decepticon one to Counterpunch's...
So, any thoughts? How'd I do for my first time?
