Please help identify traditional Chinese painting

Starting from the seal script, the left character is either 歡 or 觀 (from 趙孟頫 as well). I can't guess which one because the top-right part is blurred. As for the right-hand side one, I don't know much, but I'd say that there is either the radical 羽 which looks like or , or the radical 羊 (趙孟頫) (if we don't consider the seal's border as an integral part) in seal script. I can't identify the component between them so that the whole character makes sense to me, but @dROOOze's guess looks like the most meaningful (歡敬): . However, the lack of the right-hand side component 攵 of 敬 in the picture makes me doubtful.

Concerning the cursive script above, I agree with @Asule's answer which is justifiable: 觀 我 (趙孟頫).

It could be 茗家， seems to me that there is something above the 名

As for the seal, my best bet is 歡都. There are many parts that are not really clear or overlap so I'm not too sure for that

They are "观我", which means "look at me". My grandfather is a professional calligrapher. He writes lots of different works. And I learned a lot from him. Thank you.
