It's fine for an Eurasian Skylark. I know it's crest looks a little more obvious than usual - just a 'bad hair day', perhaps wet and partly alarmed.Crested Lark has an even longer, fuller and more triangular crest.
This whole bird is longer & stretched compared to Crested .This difference in shape is partly due to the tail being proportionally shorter in Crested.
The primary projection is long in keeping with Eurasian, the primaries barely project beyond the tertials in Crested.
In flight look for the white trailing edge - a key feature in Eurasian.
Crested vary hugely between races, but as far as I am aware all races will have rufous underwing coverts and no white on the wings.
Nice Photo.
Best wishes,
