"I like the way you tackeled this" Implies the work has been done successfully. ", have you thought about this approach?" is trying to imply that the work is not sufficient actually without actually saying that. Your message has taken a complete 180 since the first half of the sentence but you haven't given the listener any clues because if you use a word like "but" it might hurt the facade of niceness. It's mixed messaging. But I think a lot of the issue here is because were talking about a made up example. If we just add a little more detail to the made up response it clears up a lot of the ambiguity and makes it sound less contradictory. "I really liked how you tackled [X Requirement], have you thought about [Y Requirement + approach]?"
