These are far from bad if they're your first constructions. The O was a little too symmetric of a solve and I couldn't get a clean logical solution for the M, but neither were terrible, and the I was definitely well-crafted.

I wasn't trying too hard to avoid logical oversights, but I think they're all unique now.

I'm guessing from the inconsistent positioning of the clues in cells that these are MSPaint-made? I've heard of people without anything sophisticated having more luck with Excel; it's probably quicker.

Nice puzzles. Since the clues are close but I failed to find the solution without paper, I'd rank it 2.0-star in my system.

You might want to try using Excel, as MellowMelon suggested. Soon, if glmathgrant comes here, he'd suggest you to use OpenOffice. Either way, use a spreadsheet program.

This entry makes me remember to finish my puzzle in queue...
