Great images!

StoopidDonky: That looks certainly great . Might want to play a bit with shader networks to enhance the look and feel of the image. I like pretty much the depth of field effect in the bottle (and the refraction? itself)

crgowo: Pretty realistic image! I have a question though: Why does the gravel blur as if it has D.O.F effect, but the metal border of the aquarium don´t?

Pretty great submissions both!

Keep on them!
