Well, if you're looking for criticism, then you should start making some bad cards, because, I really like all of these. There are some teeny-tiny grammar issues (missing apostrophe in Frost Maiden's Special Summoning effect), but those are easily taken care of. I hope you manage to expand this set, possibly add a couple of Trap cards, and/or finish this as you see fit.

Thank you

You're too kind.

I added 1 Trap Card and Frost Warrior.

Nice, nice. Frost warrior is a sneaky card, I almost didn't spot the fact it would make the XYZ Summon of Frost Lady so much more easier. That's really going to help this set get its stronger cards out, and it can hold its own with 1900 ATK.

FT - Hypnotic Dance is a nice trap card for getting rid of your opponent's pesky Level 8 monsters. I don't know if this is just me, but grammar-wise, the effect should read "...from your hands, then destroy 1 card..." (I looked at some of my newer cards for this one xP).
