I also think it looks fine. Here's what I believe you have:
King Charles I, shilling, Tower mint, class 4C. Crowned bust of king, Aberystwyth style with single arched crown and large denomination behind bust, mintmark anchor. Reverse - Square topped shield over cross. Spink 2796 (2792). I'd push the date closer to 1642 (the year when the Tower mint came under control of Parliament during the Civil War).
