Well I’m one of those newbie’s who has no idea what he is doing. I'm still working on my first tank and i know for a fact it will have faults. However I’m happy for people to point them out to me, just so long as they are happy if i decide take no notice. Some detailing i have done, some i might do if its pointed out..Others i might decide are above my skill levels.
Sure point out errors, many will want pointing in the right direction, but please don't jump down peoples throats about it. People need to remember that everyone is different, some don't give a toss for detail, some lose sleep over it but we all have one thing in common, this madness called an hobby
Now where is my beer and my paint brushes

If at first you don't succeed, destroy all evidence that you tried.
