Finally my hand start to get inchy and took half of my weekend to do my 1/100 Gundam EXIA. This is what I do below.
Unfinish painting 1/144 exia at the left compare with 1/100 without painting.
Think still got alot work have to do on the small one cos the color for red is not that suitable. And I got to buy lime green for their eye and yellow for the chest. Anyway... enjoy doing this.
