Most of my work, including the watermarked photos of mine, are at a current resolution of 300 dpi, and the one I'm currently looking at (I haven't made a listing for it yet) has a pixel size of 4277x2829 pixels. Big photos! 72 dpi sounds good though, but I'm not sure what I oughtta shrink the canvas size down to in order to not make it look like a complete mess.
I made my logo in Photoshop, too :) Found a few neat fonts, spent awhile mixing and goofing around trying to come up with something nice, and what's on my shop currently is the result. It was a lot of fun, if frustrating, but the end result feels worth it! Much more fun than "real world" work, I completely agree :)
And thank you Sharon, you caught me just as I posted the above message! The reason why in some of the photos the watermark is more of an obstacle is because the watermark actually got "lost" among the background of the photo in some instances, which kinda defeated the purpose of having a watermark in the first place. I'll admit, some photos (Like the "Velaster" photo I have in there) have the watermark as being WAY too clear and too visible. It does block the image, and it's a problem I'm going to be addressing as soon and as ably as I can.
Hopefully, that'll help get me into a few treasuries! ...And to be honest, I've gotten into one, and it made me feel all giddy. It was a lot of fun! I really ought to make some of them, myself. :)
As for the comment about posting in teams, your point on how to interact with a team, to participate and mingle rather than solely and soullessly advertise, is a very good point. That's how I *imagined* it works, since if I were a random guy looking at all these threads, I'd probably pass one by if it looked simply like an ad.
What I'm hoping for is exactly what you'd mentioned; that by adding more to my favorites and circles and such, that more people see I take an interest in their work, and so they take an interest in mine. Which works out nicely, because I've seen quite a bit that I can't *NOT* look at and favorite.
