Initial Icon from 3000

I've decided to rework some of my projects from last semester now that I have a better grasp of the software.
This is the first project from 3000. It's a logo created from my initials, which are R.M.
Criticisms and praise are equally appreciated.

Ta-da.
Too simple?

Progress

So, here they are. The backgrounds include a spell book, a cauldron, a broom, and a potion bottle. I just realized that I actually forgot I had done the castle tower...so...if one of these is weak, lemme know if you think the castle tower was better. Maybe use the castle for the title card??
I'm not crazy over the broom background...
The little guy on the right is the set icon :)
Reverse side will be coming soon... Once again, feedback is GREATLY appreciated, as well as suggestions (especially for the title postcard!)
PS- I realize that the back foot on Enlarge is not filled with white...copy error ^_^

So, finally a bit of direction...Now, each postcard will have some sort of magical item (in this case, a castle tower) in the background, along with the swirly-star design. Feedback greatly appreciated!

Eh...

Not satisfied. Thoughts/opinions/suggestions greatly appreciated.
I feel like it's way too busy...

Check out the icons.

Some I like, some I don't like...however, maybe some inspiration for how to elaborate your own designs for the postcards?
