HELPITTY HELP HELP

so I really am in with these invites from whiteaisle.com


BUT I'm doing pocketfolds and with the cost of DIYing pocketfolds ($350-400) it would totally throw off my budget to purchase these as insert invites...not to mention they don't meet the measurements...so in true DIY fashion...I'm trying to come up with a design as similar to this as possible. If I can find some artwork like this my sis can hook it up into an invite...trouble is I'm not finding illustrations that WOW me.

can anyone help?

I'm looking for tree illustrations, leaves, branches with leaves fall botanicals...anything like the above or below



so far I found this

but its not as striking as the graphic on the whiteaisle invite.
