Hey y'all, I just found this site (wtf have I been?), amazing stuff.
I thought I'd contribute a few from my collection, I love using SU for organic modeling, in fact I have a garden pack of low poly vegetation available too.
Anyway, being a kid at heart and having to much time on my hands (read thank you recession with sarcasm) I decided to try my hand at cartoons in SU using a few plugins like SDS, FFD, Surface tools, Booltools, etc.
I moderate at a site that's all sketchup, possibly the most active SU sites with lots of tutorials and especially lot's of live help. Just ask a question and before you know it there will be a few answers.
I hope the mods here do not mind me posting the link as this is really a site that can help, there is a newbie section where any question relating to SU will be answered no matter how siilly it may seem.
