I was wondering if you built this model. This model needs a lot of careful fitment to look good, otherwise it looks like one of those "almost got it" models, as there are usually huge seams and ill fitting parts. RocketmanTan tends to bang out his models. This gets some unusual models out there, but not paying attention to the details usually means lots of work that should have been done by the designer is not done, and when I see the Beta models he has built on lots of his models, those same gaps and ill fitting seams are there. It's just a warning and caution that to get the best out of this model, you may find yourself making quite a few adjustments.
One, right off the top of my head is the top box shape and the piece that goes down the back should have been made longer, a hole cut into the fuselage and the piece slid through, there would be not gap, but you can even see in the picture how bad it fits. The flat piece around the mid section of the hull is problematic because he rarely uses formers. There are pictures at paper modelers that show this.
The pic below shows a model I would throw away if it came out that way. IMHO. It would be possible to turn this into something nice, but just realise that going into it. One with separated seams and ill fits, well honestly, at this stage of the hobby, unless you're very new at this, it shouldn't be acceptable, unless you're making a toy for your kid to crash and burn with. Making even a sub par paper model takes much time and effort.
