I think the sketch challenge is called such for a reason! I am thankful that Roxie takes the time and effort to do this for us! I too think that if a sketch is posted, it should look like the sketch, hence the challenge. And if you find it hard, again, CHALLENGE! I don't card if it is tweaked, BUT I also think we should be able to EASILY pick up the sketch. The cards today have been GORGEOUS! Thanks for posting so I could comment on your creations.
Just my opinion, and I'm not posting this to try to start a war, just voicing MY opinion, not necessarily that of others!
