Nice rose, your camera is hella blurry tho.
Your simples look nice you just need to keep churning them out and changing them slightly and learning when stuff is off. The advice i got was to make all your bars even and the same size, experiment with different words if you like, become familiar with what makes the letter unique.
With bubble writing its the same thing, keep your letter widths equal.
Best to experiment with 3D and shadow once you feel that your letter shapes are solid but dont put it off, u want things to progress at an equal rate.
Also, get involved as soon as u can with the battles dude, its a toy battle, no one is gonna burn you. Plus gives u an incentive to up your game.
My 2 cents.
