Firstly, thats a fantastic idea, and I am nicking it!!!
Overall this is a very good mini. Your brush control is very neat, and the gold braclets are well done (with nice levels of shading and highlighting).
Roger hit the nail right on the head though- you need to take your highlights up. The base edging also lets the mini down. I can see where you were going with the dags but they need to be a lot neater to work especially for competitions- also if you wanted to do dags then filling one of the lines in with a bold colour works really well,
I personally think that a plain black rimmed base would have worked better. Also regarding the base, perhaps have him sat on a bigger rock would have had more impact, and a few more details may have helped too.
I love his beer mug- how did you do the froth?
Hope this has been helpful, and thanks for the inspiration.
