I agree both with Daver's critiques and his constructive comments. Great idea, big potential, but not the greatest execution. Like he said, it's a sloppy paintjob, but I love what you were going for here, and anyone attempting a Croc Master custom is cool in my book.
I can already tell you're getting much better with that Lobo you just posted...that one came out sweet.
Luckily, these forums are a great place to get honest feedback and expert advice from people who want to help you get better, as opposed to dicks who just point and go OMGUSUXLOL.
