Hi aviel08,
I think it’s really a good start, for my tastes too much frigne value (in Photoshop I always use chromatic aberration, but in Unreal even using minimal values gives too strong results), the external texture seems not match the light intensity of the environment, did you try to add the texture to the emissive pin of the material? (maybe better with a multiply node attached)
…can come out a great material, have you got its normal and specular map?. Can you share the settings of your glasses material?, I’m not able to produce a sligthly colored front color glass with strong color at its sides…even the frosted glass is so painful for me 
Cheers,
