I also think the descriptions should be at the autor's election. There are some pics explicit at clear enough to understand what's what and what's happening there, though a lot of pics are not, in those a description would really help the viewers. In general is cool to see a background story or the intentions of the autor to know what he was trying to achieve and some tips to do it.

I also agree with zedhatch about the fun. Even if making dios is how you make your living (is that even possible? I'd like to, hehe), you should try to have fun with it and if you are going to post your work somewhere, be ready to receive critiques. To criticize is something good and should be encouraged, it has nothing to do with being an offensive troll and everything to do with being critic (evaluate, analize, point out good or bad things). It's a reality that not everyone is going to like your work, whether that be a mere liking even when the work is outstanding (i.e. "I don't like dreadnoks at all") or 'cause it isn't a good work.

And lastly, I think the noobest of noobs can also come with a great critique or comment, you don't have to be an expert to notice something wrong or to know something that might help the autor. People should always try to say something useful here, but it has nothing to do with your dio-resume...
