Bolder colours than I've used for a lot of these, but the contrast can't be a bad thing.
I did start off unsure how I wanted to structure my 4. In the end, the slanted version is a clearer silhouette, so it made sense to go with that.
I think some of the features I ended up using in the design were quite tool-like. There's even a catch from my son's pram in there.
So, number 4. I finished this just in time to use it to announce my 40th birthday, which is a bit egotistical, but I can live with it.
