Question

this is what I was thinking while looking at colagene.com... I found this website while reading a Canadian graphic design magazine looking for an article. This is what I will do for my assessment. When looking at this website some designs attract me and others were really busy.... So this is where I found the question: Is their such a thing as too much design? and when can you tell the difference? I really can't other then what I visually prefer...
Here are some examples:

kimi kimoki

mydeadpony

chris arran

geraldine george

The two in the middle I find like its a lot in the compostion. Looking at these works will help with my work because it will show me my preferences and it will also help me when i make compositions.
