Not bad so far, off center the driftwood to the left...i would say, and clump up your cabomba either in the background or midground but not the front like you have the 2 in front of the driftwood. Get more stem plants IMO.
IMO is an abbreviation for "in my opinion".This may sound stupid, but what does IMO mean. I see it often but it isn't in the "glossary of terms".
