Layers of colour 1

One of my aims in the next few weeks is to play more with colour in my etching. At the same time as I  made the last 4 plates I also made some simple etched plates which I intend to use as multi plate prints as this is something I haven't dome for a while. 
Once again this post is about what went wrong rather than what went right. I had problems with so many things in this print. For a start, while the plates appear to be the same size,  clearly there is a slight difference ( cut by hand not purchased at a specific size). Secondly there  was too much pressure from the press which you can tell if you look closely at the edges of the plate as the paper has sort of cracked. And then there's the whole issue of the colour- which is muddier than I intended. I wanted bright shades. 
To be honest when Iook at this I relaise that I'm not at all happy with the 'back' plate. I'll probably re etch that to give more lines.
More work needed.
