Just got inspired to try an under the sea piece.
I didn't want to use a background. So I tried making my own ocean. It's my first, so it may be off a bit. I think it came out pretty well though, for my first.

I was originally going to have a sea bed and not have the "camera" facing at an upward angle. On the sea bed I was going to do a shipwreck, but I went a different way as you can see. I may do the shipwreck another time.

An underwater city came to mind and I thought Rome would be a nice. (I hope it doesn't flood in the near future. I'd like to visit there sometime.) You don't see the rest of the city since the Colosseum is there and the "camera" is facing upward. I think creating the underwater wave ripples was the hardest part for me. OR maybe making the Colosseum look like its icky and underwater...

I hope you guy's enjoy it.
Thanks!
