I really wouldn't do the anglefish if I were you, you have to use a paper that's the same colour on the both sides, because the model kind of reverses half way through but you can't tell because mountain valley folds are not marked in. I haven't tried the butterfly yet but it might be a better choice ifyou switch models.
Frankly, I had no idea this model was diagramed and probably would not have ever found out if it hadn't been for this topic, and it might not be a good idea to change it. If you do, then a simple model would be better to fit into the shorter time for the rest of the month.
If you win you can always suggest these models some other time c:
I don't see a problem with using the lion, if you use the diagram you are only cheating yourself really. It's not like there is a cash prize, is it. Cheating would be kind of odd behaviour...
I agree with Edg and jsrn. It's not a competition with prizes, but only fun. If someone doesn't want to be satisfied with folding this model from cp, that's his problem.
