Appeal: This is a really excellent signature, with great colours, composition and appeal. While simple and uncomplicated, it has a calm atmosphere about it and really does look nice; I'd say this is definitely one of your best looking. The only shabby part of this smudge sig is the text, and while it does knock the sig of its feet a little, it's not too bad and can be easily fixed.
Execution: I'll be honest here; this is one of the best smudges I've seen. I can't call it unique, but it's definitely turned out great; the smudge and colours are just right. The only slightly uncertain bits of the sig is that it's a little oversharpened and as mentioned before, the text is a little off.
Comments: Can't say more than I have already. You're improving at tremendous paces, and while your style isn't original or unique, your signatures are coming out very nice looking and appealing. This is definitely the best I've seen from you yet.
Tips to improve:Keep working on your text... look up as many text tutorials as you can, and regularly get new fonts and experiment with them. Also, slowly start tearing away from the conventional signature styles and explore on your own with handmade vectors, serious photomanipulations and just plain abstract pieces.
