Merely Okay...
Your Flash style is certainly unique, but the characters/environments lack fine detail. Your backgrounds are (presumably :-) ) intended to appear three-dimensional, but your characters (as well as some environments) epitomize the unrealistic "flatist" artistic style popular in the mid-20th century. Take more care with your drawings (I.E., add textures, correct perspective distortions), and this would become Top 50 material.
Nevertheless, your animations have a certain "magnetic aura," if you will: I have watched "Auf Achse" seven times!
