The first is fine, because it's a standard construction, the same as 'Make it nice' or 'Make it quick' . In this sentence 'interesting' is an adjective, not a verb. The second is strange. It isn't normal to use 'make' followed by a past participle in a causative construction. You can say 'Make someone do it' with the base form, or 'Have it done' or 'Get it done' with a past participle.

Thank you, so helpful!
