Progress is slow & opinions please!

I thought the hedgehog in the cup would make a cute embroidery pattern so about 2 weeks ago I started drawing, then last week I began stitching but progress has been sloooow. I made some odd stitch and colour choices so I have been unpicking more than I have been embroidering. Wait...that isn't possible...but it feels like that anyway. First Hedgie was floating in a pea-green sea (not a good idea) in a cream coloured split stitched cup. I unpicked the split stitch and used a back stitch but the cream colour still did not look good  because of the naturel cotton colour of the fabric. So I re-stitched (if that is a word) the cup in a lighter shade of blue which is a much better choice. The only thing that worked out fine instantly was the red/white border for which I used a whipped back stitch.

Now this Hedgie pattern tryout got me thinking and I am wondering if I should add something like a stitch or colour advice with my patterns. Or on this blog. What do you all think?
