Google Algo - Webmaster Tools - UK Domain Forum Acorn Domains

After the recent EMD / Penguin algo change, has anyone seen any message or warnings in the Webmaster tool pointing at reasons for any downgrade or loss in traffic?

I'm noticing my inner pages are going up in the SERPS. After 27th September they were around 11th and 12th pages - now they are 5th and 6th pages. My index page though is still nowhere to be seen (was in 2nd spot for a good keyword).

I'm guessing this is a penalty or sandbox (rather than an EMD drop) due to Penguin but I was strictly whitehat with everything I did.

Other than webmaster tools, anyone know of anywhere I can check my site over for potential issues (harmful inbound links, bad internal structure etc....)?
