is this a difficult pattern?

[barefootgenius.livejournal.com]

I'm in love with puffy sleeves, and I want to make this http://www.simplicity.com/assets/5872/5872fb.gif ("C"). This will be the first shirt I'll be attempting; until now, I've sewn a bunch of skirts, though only a couple are wearable.

Is this too difficult a shirt pattern to start with?

Thanks muchly :)
