Game Asset Pack

Hey Boxers!
I am currently making a game asset pack and wanted to to hear some ideas on what to add to the collection. It can be anything characters, environment, etc. I will try to turn these ideas into good quality graphics that you can later use in your games for free (I will also be adding some animations for characters and points/coins)

So just comment some ideas and I'll be on it as soon as possible!

 

Now the theme is Halloween.
In a few months Christmas.
After New Year.
Valentine's Day.
St. Patrick.
Summer.
...
Sports are always good.
Football.
Baseball.
Rugby.
Moto GP.
F1.

Car or motorcycle designs are very interesting for games created with BB.

 

I always find it hard to find ideas for explosions and coin collections.

 

Thanks for all the suggestions!!

 

Thanks Aaro, I will be getting my hands on it!
