I didn't mind splurging a little on the set. It is expensive, but the parts are an improvement over the kit parts. Whether the improvement justifies the cost is another matter. Here are some pictures comparing the resin to the kit parts:
here's my completed one:
Your model there looks very nice indeed!
And yes, when you put the parts side by side, you can see which one has the greater detail, and it is the Eduard part.
My point is that had you stuck with the Tamiya engine parts, once the entire plane was finished, one would not necessarily notice a lack of detail coming from the engine compartment. To the eye it would seem suitably detailed and busy and it would not stand out as a weak point of the kit.
So does adding the Eduard extra detail improve the kit? Sort of! I would rate it very low on a list of factors that make a good looking model, however.
A very clean build, an excellent paint job with proper scaled down colors, and proper weathering are all much more important to the final appearance IMO.
PS: I have bought many Eduard aftermarket resin products with some success, some failures!
