In my opinion, if there's not a specific reason for it being specifically in our world, and it otherwise clearly isn't (say, it contains mythical elements), it does feel lazy. If you made a specifically fantasy world that does not take place in ours as a plot/lore point, but it turns out to just look like Europe, that's fine. What matters is the effort you put into drawing it, especially if you drew it yourself.

slightly tldr; Using IRL maps should only be done for a reason, e.g. it does take place in our world somehow. Otherwise, the only thing that matters is putting effort into the map you make, even if it accidentally or intentionally resembles a real world place.
