Potential issue: repeated digits. This question already raised from other threads, but here it is a bit more extended, with a digit repeated 4 times.

A definite no for me - not only have you got the repeated numbers having to be placed, there is also something of a Heyawake or Hitori like constraint in terms of packing the 4's and 3's into fairly limited regions.
