These are freaking AMAZING! :D I'm speechless

I have left random testificates in at least 3 of those :P

Epic Builds! I Like the castle and the mansion! :D

Good work on the floating island. Love how you did the detailed tree. It's actually close to a professional degree, so i encourage you to keep at it ^^

Dislike the blue castle, coz circles :(

Ship could use some more detail, like fences, stairs and halfsteps. Maybe variation with the wood?

Like the mansion, could be a bit taller though. Nice combo with brick and iron (?) though. Could prehaps use some hedges or other decorative garden-type things.

PvP arena, awesome job, nicely detailed interior. Prehaps some more detail outside to somewhat smooth the outer edges so that it doesnt look too pointy. I think allowing people to access the very top of the arena might be a bit more aesthetically pleasing. Could do with some vines hanging down from some sides.

IMO, good builder with a lot of future potential. You've got good mastery of detail on trees, but I think more work is required on building detail (Eg. the castle and arena). Prehaps try using more block types, try to use mechanisms such as redstone lamps or just redstone torches, flowing water, and most importantly, excessive use of slabs (mostly smooth, coz smooth slabs = epicness), stairs (stone brick or wood = win) and fences (wooden fences!!!!!!!!!!!!)

Gotta love that first one!
