Hello Lian, I think it would be cool to have a lesson in the style of Jari Mäenpää if you are not too busy with other projects. I know that you have already covered Ensiferum a little bit with the Viking-Folk concept lessons, so maybe it could be based around his more recent material in Wintersun.

yeah! it will be awesome, I am a big fan of wintersun! so, let me some time to work on it man
thanks for request!
