My first idea was a Twine game, but I've been intimidated by writing lately so I decided to avoid it here (but I'm definitely going to force myself to face that one). As for including drawings, there are a couple of games that I love that do that exceptionally well. Snowy McAlly's A Little Witch Story has polished art, but still pretty accessible (http://littlewitchstory.com/) and I think it works super well. If your art is a little rougher than that, Victorian Detective uses some rough sketches really effectively (http://textadventures.co.uk/games/view/w207ce4zeku...).
As for feels, I'd say it isn't essential for a text adventure, but art can definitely add to the narrative by setting the mood and illustrating certain things. All that to say, I'd encourage you to give it a go. It doesn't have to be every passage, just where you think it would really help (A Little Witch Story is a good model for this, too.)
