I really like the colors and textures. IMHO, this might have been improved with judicious cropping. Rule of thirds? Put the line of bubbles on the diagonal? As it is, the picture is cut in half. That's not necessarily bad.. Just my observations.
7 - Nice, fairly good angle. If it were 'diagonal', may have made it more dramatic in my opinion, but just 'sharper' angle/perspective wise - either way.
